Bug Report avcodec-57.dll, Qt5 widgets.dll, obs-frontend-api.dll, libcurl.dll was not found trying to open OBS

[Wallski]

Every time I try to open OBS studio these errors will show up after one another: avcodec-57.dll, Qt5 widgets.dll, obs-frontend-api.dll, libcurl.dll was not found trying to open OBS. If someone could help me that would be amazing! Thank you!

It seems your installation of OBS is somewhat messed up. Uninstall OBS, download the current version from the website, and install it again. Your settings/scenes will survive the reinstall.

I’ve uninstalled and reinstalled multiple times, am I not doing it right when uninstalling? Sorry if I seem bad at this, I’m new at this.

Perhaps you have another (messed up) copy of OBS somewhere on your pc, and you are always starting that copy instead of the copy you just installed fresh.
Make sure that after uninstall, every trace of OBS program files, dlls, desktop shortcuts and start menu shortcuts are gone as well. If they are not gone, delete them manually. Then reinstall and make sure you start OBS with the shortcut the installation program just created.

I will try this, thanks!

It says that the shortcut has been moved or changed and it asks me to delete it. It still won’t open.

You can unpack the https://github.com/obsproject/obs-studio/releases/download/21.1.2/OBS-Studio-21.1.2-Full.zip into any new folder you made (for example: "C:\Program Files (x86)\obs" or just "C:\obs", then you need to navigate (via file explorer) to "bin\64bit\obs64.exe" (the file with black obs icon inside the folder you have made), right-click over it and choose the option to Send to desktop (make shortcut) - this should make new shortcut on your desktop to launch the application.
